California Motorcycle Helmet Law: Requirements and Injury Claim Implications

California Vehicle Code Section 27803 requires every motorcycle rider and passenger to wear a safety helmet whenever riding on a public road. The helmet must meet the federal Department of Transportation (DOT) helmet standard, FMVSS 218, adopted under Section 27802. California is a universal helmet law state. It applies to riders and passengers of all ages, with no age-based exceptions. Not wearing a DOT-compliant helmet is an infraction. In personal injury claims, not wearing a helmet can be raised as comparative fault. Attorney Damoun Yazdi handles California motorcycle accident injury claims throughout Southern California.

Key Takeaways

• California Vehicle Code Section 27803 requires all motorcycle riders and passengers to wear a DOT-compliant safety helmet on public roads, with no age exceptions in California
• A helmet must meet U.S. DOT FMVSS 218 standards and display a DOT certification label on the outside rear; novelty helmets without valid DOT certification do not comply
• Failure to wear a helmet is an infraction under CVC 27803, punishable by a fine; the total amount owed is typically higher than the base fine once state and county penalty assessments are added
• In a personal injury case, if you were not wearing a helmet and suffered a head or neck injury, the at-fault driver may argue comparative fault, but California’s pure comparative fault rule still allows you to recover damages even if you were partially at fault
• Under California’s comparative fault rule established in Li v. Yellow Cab Co. (1975), helmet non-compliance can reduce but never eliminates your recovery, and it only affects damages attributable to the specific head or neck injuries a compliant helmet would have prevented

What Makes a Helmet DOT-Compliant?

A DOT-compliant motorcycle helmet must meet Federal Motor Vehicle Safety Standard (FMVSS) 218, a performance standard enforced by the National Highway Traffic Safety Administration. NHTSA does not mandate specific materials, but its testing experience shows that helmets meeting the standard share common, identifiable characteristics:

• Weighs approximately 3 pounds or more
• Has a thick inner liner, generally about 1 inch of firm polystyrene foam
• Has a rigid outer shell
• Has a sturdy chin strap with solid rivets
• Bears a DOT certification label on the outside rear

California law enforcement can cite a rider for wearing a helmet without the DOT label. Helmets that do not comply include novelty helmets (thin shells with no inner liner), bicycle helmets, skateboard helmets, and helmets bearing counterfeit or misapplied DOT stickers that do not actually meet the standard.

Helmet Non-Compliance and Your Injury Claim

Under California comparative fault, if you were riding without a helmet and suffered a traumatic brain injury (TBI), skull fracture, or cervical spine injury, the at-fault driver’s insurer will argue your damages should be reduced based on your failure to wear protective equipment. Attorney Yazdi works with accident reconstruction and biomechanical experts to establish precisely which injuries a compliant helmet would have prevented, which limits the comparative fault reduction to only those specific injuries.
